What Is the Atlas-C1-A?
The Atlas -C1 is a precision-engineered, stainless steel tool designed to counteract the mechanical force of 130–140 lbs. of string tension typically exerted on the vulnerable headstock/neck junction of all (3-on-3) six-string guitars tuned to standard pitch (440Hz). When properly fitted, the Atlas -C1 ensures a net force of zero—achieving static equilibrium exactly where it’s needed on the instrument—providing unparalleled protection.
The innovative design of the Atlas -C1 accommodates all (3-on-3) six-string guitars with nut widths up to 50mm and break angles from 10 to 28 degrees. Patented and trademarked, this tool is simple to use—requiring only finger-tightening until securely in place. Avoid excessive force or additional tools, as they are unnecessary for the Atlas- C1 to function effectively.

How Does It Work?
Stringed instrument designs with headstock break angles are subject to a high pressure, forward directional force right at the vulnerable headstock/neck region when tuned to pitch , typically 440Hz, and that pressure measures in at 135 lbs. + or - several lbs. That pressure creates a condition known as "loading" right at the weakest point of the neck design, and why they always break in a forward trajectory, unconvinced? simply Google "Broken Headstocks". To have a better understand of this pressure perspective, visualize picking up ,simultaneously two 60 pounds sacks of concrete and a bag of sand as a topper.! With that in mind you can truly understand what guitars must constantly endure and why so many are seemingly so easily broken . They really need any additional protection we can afford them! Over time, this continuous force can also lead to other unintended consequences. The headstock/neck junction may warp or twist -all depending on how and where the instrument is stored and cared for making the Atlas-C1 an invaluable essential tool for instrument care.

The Atlas- C1 stabilizes the weak head neck junction of a guitar by applying an equal opposing force to the string tension while the instrument is strung to pitch and acts as a proactive guardian at all other times. Using the Atlas- C1 significantly reduces the risk of damage from accidents or mishandling. Transporting a stringed instrument can be risky even under controlled conditions , but accidents happen even then. By using the Atlas- C1 you can greatly reduce the probability of damage through a proactive approach to instrument care safeguarding it wherever you go.

Why Is It Called Atlas-C1? Well:
In Greek mythology, the Titan Atlas symbolizes strength and endurance. Similarly, in human anatomy, the Atlas (C1) vertebra stabilizes the skull at the top of the spine. The Atlas C-1 tool echoes this role by supporting the vulnerable headstock-neck junction of stringed instruments. It delivers targeted support at this critical area, offering unparalleled protection to the headstock/peghead of most 3-on-3 six-string instruments.
